Семинар на секция ИОВС и Семинар по оптимизации на ФМИ – СУ

Институт по математика и информатика - БАН Block 8, 1113 БАН IV км., София

На 1 юни 2026 г. (понеделник) от 14:15 часа в зала 503 на ИМИ-БАН ще се проведе съвместно заседание на Семинара по изследване на операциите на ИМИ-БАН и Семинара по оптимизация на ФМИ при СУ "Св. Климент Охридски". Доклад на тема On the subregularity of mappings associated to optimization problems ще изнесе Alberto Dominguez Corella, University of Graz, Austria. Abstract: This talk is meant as a nontechnical discussion on the concept of metric subregularity and its application to the study of stability in optimization problems. It features equivalences between the property and local error bounds, as well as theoretical applications, e.g., discretization, approximation, and differentiation with respect to parameters. We describe several concrete applications, including inverse problems and optimal control. The talk will be based on several joint [...]

Поредица от лекции по теория на представянията и математическа физика – Иван Димитров, лекция 3

Институт по математика и информатика - БАН Block 8, 1113 БАН IV км., София

ICMS Distinguished Lecture series in Representation Theory and Mathematical Physics Дата и място: May 19 and 21, 2026 (15:00–16:00 Sofia time) and June 1, 3 and 5, 2026 (16:00–17:00 Sofia time), Room 403, IMI - BAS Лектор: Ivan Dimitrov (Queen’s University, Canada) Тема: Root systems, generalizations and applications Root systems were introduced by Wilhelm Killing in 1889 as a tool for classifying Lie algebras. Since then, they have become ubiquitous, appearing in various contexts in seemingly unrelated areas of Mathematics. In this lecture series, Ivan Dimitrov introduces and studies root systems and defines a generalization of root systems. He explains how this more general structure applies to various problems, e.g. hyperplane arrangements. Finally, he introduces and studies inversion sets of roots. The exposition is [...]
